FIELD

Embodiments described herein relate to a bag storage case.

BACKGROUND

As a device for performing settlement processing by a customer, aself-checkout device and a settlement device are known. For example, theself-checkout device is a device for reading information of a commodityby the customer himself/herself to perform settlement. For example, thesettlement apparatus is an apparatus for allowing the customer toperform only the settlement.

The commodity which has been subjected to the settlement processing byusing such a settlement apparatus is placed into the bag by thecustomer.

Such a bag is called a register bag, and for example, a clerk who is incharge provides the register bag to the customer.

In addition, in recent years, there has been a case where the customerbrings a bag, and the bag is suspended around the settlement apparatus.

In view of hygiene, there has been known a technique for accommodating aplurality of bags stacked on a drawer shelf such as a holder, and atechnique for folding a plurality of stacked bags to be accommodated ina holder. When the bag is contained in such a drawer shelf or holder, itis required that the bag be visually recognizable so that the size andremaining amount of the bag can be known. However, when the take-outopening for taking out the contained bag is large, a plurality of bagsmay be taken out at a time, and when the take-out opening is small,there is a problem that it is difficult to take out the bag.

As shown in FIGS. 1 to 3, the bag storage case 1 includes a housing 11and a holder 12.

The bag storage case 1 accommodates a plurality of bags 100 in thehousing 11 in a state in which the plurality of bags 100 are stacked andheld by the holder 12. The plurality of bags 100 are held so as to beable to be taken out in the state in which the plurality of bags 100 arestacked by the holder 12.

As shown in FIGS. 4 and 5, for example, the bag storage case 1 is formedso as to be stackable with additional storage cases.

In the first embodiment, the bag 100 is a so-called “register bag”. Thebag 100 includes a main part 111, a pair of handles 112, and a hung part113. One end of the main part 111 is closed, and the other end is open.The closed end of the main part 111 forms the bottom of the bag 100. Theextending direction of the closed end edge forming the bottom of the bag100 will be described below with reference to the width direction of thebag 100.

The pair of handles 112 are integrally formed on the other end of themain part 111 on an opening of the main part 111 of the bag 100. Thehung part 113 is provided at one end of the opening of the main part 111and between the pair of handles 112. The hung part 113 is formed, forexample, with a hole 113 a.

The hung part 113 is integrally provided with the main part 111 so as tobe separable from the main part 111. As a specific example, aperforation or the like is formed at the boundary between the main part111 and the hung part 113 to separate the hung part 113 from the mainpart 111.

For example, a plurality of bags having different widths are used as thebags 100. As a specific example, three types of bags 100 having anL-size having a large width, an M-size having a middle width size, andan S-size having a small width are used. For example, the L-size bag 100has a width of 320 mm, the M-size bag 100 has a width of 260 mm, and theS-size bag 100 has a width of 145 mm.

For example, as shown in FIG. 3, a plurality of such bags 100 arestacked and folded at a folded portion 150 in the main part 111. Thenthe folded portion 150 is held on a shaft 51 in the holder 12, and theplurality of stacked and folded bags 100 are accommodated in the housing11.

As shown in FIG. 1 to FIG. 3, the housing 11 includes a pair of firstwalls 21, a pair of second walls 22, and a third wall 23. The housing 11is formed in a rectangular box shape in which one surface is opened by,for example, a pair of first walls 21, a pair of second walls 22, and athird wall 23.

The pair of first walls 21 are opposed to each other at intervals inwhich a plurality of stacked and folded bags 100 are disposed. That is,the pair of first walls 21 are opposed to each other so as toaccommodate a plurality of stacked and folded bags 100. Morespecifically, the pair of first walls 21 are spaced apart from eachother at intervals in which the holder 12 for holding the stacked andfolded bags 100 can be disposed.

The pair of first walls 21 are opposed to the stacked and folded bags100 in the stacking direction of the plurality of stacked and foldedbags 100. In other words, the pair of first walls 21 are opposed to themain surface of the main part 111 of the bag 100. For example, the bagstorage case 1 is placed on an installation surface such that one of thepair of first walls 21 is positioned downward. The pair of first walls21 are opposed to each other in the height direction to form a bottomwall and a top wall of the bag storage case 1.

The pair of second walls 22 are continuous with the pair of first walls21. The pair of second walls 22 are opposed to each other in the widthdirection of the accommodated stacked and folded bags 100. The pair ofsecond walls 22 are spaced apart from each other a distance larger thanthe width of the stacked and folded bags 100 so that the plurality ofstacked and folded bags 100 can be disposed. For example, the pair offirst walls 21 constitute a pair of side walls of the bag storage case1.

The third wall 23 has a take-out opening 31 in a part thereof. The thirdwall 23 is continuous with the pair of first walls 21 and the pair ofsecond walls 22. The third wall 23 includes, for example, a firstinclined part 32 inclined to the opposing direction of the pair of firstwalls 21, and a second inclined part 33 inclined with respect to theopposing direction of the pair of first walls 21 and inclined in adirection different from the direction of the first inclined part 32.Hereinafter, the “opposite direction of the pair of first walls 21” willbe described as the “first direction”. When the pair of first walls 21constitute a bottom wall and a top wall, the first direction is thelateral, or vertical, direction.

As a specific example, the take-out opening 31 is provided in the firstinclined part 32. The take-out opening 31 is opposed to the foldedportion 150 of the plurality of stacked and folded bags 100 accommodatedin the housing 11.

The take-out opening 31 extends along the opposite direction of the pairof second walls 22. Hereinafter, the “opposite direction of the pair ofsecond walls 22” will be described as the “second direction”. When thepair of first walls 21 constitutes a bottom wall and a top wall, thesecond direction is the longitudinal, or horizontal, direction. Thewidth in the longitudinal direction of the take-out opening 31 issmaller than the width of the bag 100. Further, the center, or middle,of the take-out opening 31 is larger than both end sides of the take-outopening 31 in the first (i.e. vertical) direction. That is, the take-outopening 31 has a wide center or middle and narrow ends in the firstdirection. That is, the width of the take-out opening 31 in the lateral(i.e. vertical) direction is different between the center or middle andboth end sides, and the width in the center or middle is larger than thewidth on both end sides. Further, the take-out opening 31 is set to havea constant width in the first direction in the center or middle and aconstant width in the first direction on both end sides. Moreover, thetake-out opening 31 is formed to have a curved corner portion.

As shown in FIG. 4, the length of the take-out opening 31 in the seconddirection, that is the length in the longitudinal direction, is set bythe width of the bag 100. As a specific example, as shown in FIG. 4, thetake-out opening 31 is formed of a first opening 31 a provided in thecenter or middle and a second opening 31 b provided on both end sides inthe second direction of the first opening 31 a and continuing to thecenter or middle in the first direction.

For example, the width of the first opening 31 a in the second directionis constant regardless of the width of the bag 100.

The width of the second opening 31 b in the second direction is smallerthan the width of the bag 100, and is set as appropriate based on thewidth of the bag 100. For example, the width of the second opening 31 bin the second direction is set as a function of the width of the bag100.

The first inclined part 32 is continuous with the first wall 21 formingthe top wall and the second inclined part 33 in the first direction.

The second inclined part 33 is continuous with the first wall 21 formingthe bottom wall and the first inclined part 32 in the first direction.

That is, for example, the first inclined part 32 is positioned above thesecond inclined part 33.

The first inclined part 32 and the second inclined part 33 are inclinedin a direction away from the first wall 21 toward a center side in thefirst direction from the first wall 21 side.

In other words, the first inclined part 32 and the second inclined part33 are continuous at the center side in the first direction, and thecontinuous portions of the first inclined part 32 and the secondinclined part 33 are protruded from the outside of the housing 11.

In other words, the third wall 23 is formed in a shape that is chamferedby the pair of first walls 21, the first inclined part 32, and thesecond inclined part 33.

Such a housing 11 is formed, for example, by integrally molding a pairof first walls 21 and a pair of second walls 22 in a rectangularcylindrical or parallelepiped shape, and by covering one of the openingsformed by the pair of first walls 21 and the pair of second walls 22with the third wall 23. The front side of the case 11 is formed by thethird wall 23, and the rear side is formed by the opening on theopposite side of the third wall 23.

Note that the housing 11 may be configured by assembling a panel thatforms a pair of first walls 21, a pair of second walls 22, and a thirdwall 23 on a frame having a rectangular parallelepiped shape.

Further, the housing 11 may be formed by integrally molding a pair offirst walls 21, a pair of second walls 22, and a third wall 23.

As shown in FIGS. 1 to 3, the holder 12 includes, for example, a tray41, a holding part 42, and a guide part 43.

The tray 41 is formed in a rectangular cylindrical or parallelepipedshape which is in contact with the pair of first walls 21 and the pairof second walls 22.

For example, the tray 41 is configured such that a wall portion of thetray 41 that forms an upper wall of the tray 41 is opposed to the firstwall 21 and can be opened and closed.

Note that the tray 41 may not have the wall portion opposed to the firstwall 21 forming the upper wall, for example as shown in FIG. 8.

The tray 41 has a width equal to or slightly larger than the width ofthe bag 100, between inner surfaces of a pair of walls opposed to thepair of second walls 22.

The tray 41 is insertable into the opening on the back side of thehousing 11 and is removable therefrom, so that the tray 41 can beattached to and detached from the housing 11.

The tray 41 accommodates the plurality of stacked and folded bags 100held by the holding part 42, and the front side and the back side of thetray 41 are open so that the plurality of stacked and folded bags 100can be inserted and taken out.

The holding part 42 is provided, for example, in the tray 41.

As shown in FIG. 3, the holding part 42 includes a shaft 51 forsupporting the folded portion 150 of the plurality of stacked and foldedbags 100, a support plate 52 for supporting one end of the plurality ofstacked and folded bags 100, a hanging part 53 for hooking and holdingthe hung parts 113 of the stacked and folded bags 100, and an adjustingmember 54 for urging the shaft 51 in one direction.

The shaft 51 is disposed to face the take-out opening 31 of the thirdwall 23. The shaft 51 is supported by the tray 41. For example, theshaft 51 is supported on the tray 41 so as to be movable toward thetake-out opening 31. The folded portion 150 of the plurality of stackedand folded bags 100 is wrapped around the shaft 51 and the shaft 51supports the folded portion 150 from the inside.

The support plate 52 supports a bottom side of the plurality of stackedand folded bags 100. The support plate 52 is disposed at the rearopening in a state in which the tray 41 is disposed in the housing 11and is disposed below the shaft 51. The support plate 52 is formed at apredetermined angle with respect to the main surface of the first wall21 on which the top surface becomes a bottom plate. That is, as shown inFIG. 3, the support plate 52 supports a plurality of stacked and foldedbags 100 with the shaft 51, thereby supporting the plurality of stackedand folded bags 100 at a predetermined angle with respect to the mainsurface of the first wall 21 serving as a bottom wall.

The hanging part 53 holds the hung parts 113 of the plurality of stackedand folded bags 100. For example, the hanging part 53 is provided on anupper wall of the tray 41. The hanging part 53 includes a cylindricalpart 53 a inserted into the hole 113 a of the hung part 113, and aflange 53 b having a diameter larger than the inner diameter of the hole113 a.

The hanging part 53 holds one end of the plurality of stacked and foldedbags 100 by inserting the cylindrical part 53 a into the hole 113 a ofthe hung part 113 of the plurality of stacked and folded bags 100 andholding the hung part 113 of the stacked and folded bags 100 by theinnermost layer of the flange 53 b.

The hanging part 53 may be, for example, a hook inserted into the hole113 a of the hung part 113.

The adjusting member 54 is a biasing member that presses the shaft 51 inone direction toward the take-out opening 31.

The adjusting member 54 presses the shaft 51 toward the take-out opening31 to keep the positional relationship between the bag 100 positioned inthe outermost layer of the plurality of stacked and folded bags 100 andthe take-out opening 31 constant even when the number of remaining bagsof the plurality of stacked and folded bags 100 is reduced.

The adjusting member 54 may include, for example, a coil spring or thelike which presses the shaft 51 toward the take-out opening 31.

In the holding part 42, the plurality of stacked and folded bags 100 aresupported on the tray 41 by the shaft 51, the support plate 52, and thehanging part 53, and the positions of the bags to the take-out opening31 are adjusted by an adjusting member 54.

The guide part 43 is provided on a leading end side in the insertiondirection of the tray 41 from the shaft 51 of the tray 41.

The guide part 43 is disposed between the take-out opening 31 and theshaft 51 when the tray 41 is disposed in the housing 11.

The guide part 43 is composed of a pair of projections 43 a arrangedside by side in the width direction of the bag 100. For example, each ofthe pair of projections 43 a extends from the width of the bag 100 tothe width of the second opening 31 b of the take-out opening 31, andwhen a bag 100 is taken out from the take-out opening 31, both ends ofthe bag 100 in the width direction engage and are guided to the secondopening 31 b of the take-out opening 31 by the projections 43 a.

Next, an example of the dimensional relationship between the take-outopening 31 of the bag storage case 1 and the bag 100 configured asdescribed above will be described with reference to FIG. 6.

As shown in FIG. 6, the width (bag width) of the bag 100 is assumed tobe Fs.

The width of the first opening 31 a in the second direction is set toTc, and the width of the first opening 31 a in the first direction isset to Th1.

Further, as shown in FIG. 6, the width of the second opening 31 b in thesecond direction is set to Tw, and the width of the second opening 31 bin the first direction is set to Th2.

The dimension relation between the take-out opening 31 and the bag 100is as follows.

Fs>Tw>Tc

Tw>Tc

Th1>Th2

Further, when the L, M and S-size bag 100 is used, the size of the firstopening 31 a is set to Tc≥60 mm, and Th1≥60 mm.

Also, for example, when the width (bag width) Fs (mm) of the bag 100 isset to the variable X, and the width Tw (mm) of the second opening 31 bof the take-out opening 31 is set to the variable Y, the width Tw of thesecond opening 31 b is determined by the linear function Y=0.68x+2.2 asshown in FIG. 7.

Note that the width Tw of the second opening 31 b may be a widthdetermined by a linear function or a width that is approximate to awidth determined by a linear function.

As a specific example, in the case of an L-size bag 100 having a bagwidth Fs of 320 mm, the width Tw of the second opening 31 b is set to220 mm.

In the case of an M-size bag 100 having a width Fs of 260 mm, the widthTw of the second opening 31 b is set to 180 mm.

In the case of an S-size bag 100 having a bag width Fs of 145 mm, thewidth Tw of the second opening 31 b is set to 95 mm.

In the case of the bags 100 other than the L, M and S-sizes, it is seton the basis of the linear function.

For example, in the case of the bag 100 having the bag width Fs of 300mm, the width Tw of the second opening 31 b is set to 200 mm, and in thecase of the bag 100 having the bag width Fs of 180 mm, the width Tw ofthe second opening 31 b is set to 95 mm.

The bag storage case 1 configured as described above is arranged in sucha manner that a plurality of bag storage cases 1 accommodating bags 100having different sizes are arranged in the vertical direction, orarranged in the horizontal direction so that the take-out openings 31face the same direction.

For example, FIG. 4 and FIG. 5 show an example in which three bagstorage cases 1 are stacked in the vertical direction, the bag storagecase 1 containing the L-size bag 100 is placed in the lower stage, thebag storage case 1 containing the M-size bag 100 is placed in the middlestage, and the bag storage case 1 containing S-size bag 100 is placed inthe upper stage.

Each bag storage case 1 is arranged so that the take-out opening 31 isdirected to the customer side.

For example, the bag storage case 1 may be provided in a self-checkoutdevice or a settlement device, or may be installed in a place where acommodity purchased by using a self-checkout device or an settlementdevice is packaged.

For example, the bag storage case 1 is disposed below the customer'sline of sight.

According to the bag storage case 1 configured as described above, bysetting the width Tw of the take-out opening 31 to a proportionalfunction of the width Fs of the bag 100, the take-out opening 31 can bemade to have a suitable width to allow the bags 100 to be taken out oneby one.

Further, since the width of the second opening 31 b of the take-outopening 31 can be set to the optimum width according to the width of thebag 100, even when a bag 100 having a different bag width is used, thebag 100 can be taken out from the take-out opening 31.

In addition, the take-out opening 31 has a constant shape irrespectiveof the width of the bag 100 to perform the operation of taking out thebag 100 from the take-out opening 31.

In addition, the width Th1 in the first direction of the first opening31 a is set to be larger than the width Th2 in the same direction of thesecond opening 2 b.

Therefore, the take-out opening 31 can suitably perform the removaloperation of the bag 100 regardless of the bag width.

The bag storage case 1 is provided with a take-out opening 31 at a firstinclined part 32 of the third wall 23.

Therefore, even when one bag storage case 1 is used, even when aplurality of bag storage cases 1 are stacked and arranged, the firstinclined part 32 is positioned on the line of sight when the customervisually recognizes the bag storage case 1.

Therefore, the bag storage case 1 can improve the visibility of thetake-out opening 31, so that the visibility of the bag 100 existing inthe take-out opening 31 is improved.

In addition, the access to the bag 100 of the lower take-out opening 31is improved, and even when the bag storage case 1 is stacked, the bag100 can be easily taken out from the take-out opening 31.

As described above, according to the bag storage case 1 of the firstembodiment, by optimizing the relationship between the size of thetake-out opening 31 and the width of the bag 100, the bag 100 can besuitably taken out from the take-out opening 31.

Incidentally, the bag storage case 1 is not limited to the aboveembodiment.

In the example described above, the third wall 23 has the configurationhaving the first inclined part 32 and the second inclined part 33, butis not limited thereto.

For example, as shown in FIG. 8, the third wall 23 may not have thefirst inclined part 32 and the second inclined part 33, but may beformed in a planar shape orthogonal to the first wall 21 and the secondwall 22.

Further, as shown in FIG. 8, the holder 12 may not have the upper wallof the tray 41 and the support plate 52.

In the example described above, the plurality of stacked and folded bags100 are held by the holding part 42, and the take-out opening 31 isopposed to the folded portion 150 of the stacked and folded bags 100,but is not limited to this configuration as described above.

For example, the take-out opening 31 may be opposed to a portion otherthan the folded portion 150 of the stacked and folded bags 100, and theholding part 42 may be configured to hold a plurality of stacked bags100 without being folded.

According to the bag storage case of at least one embodiment describedabove, the bag is suitably taken out from the take-out opening byoptimizing the relation between the size of the take-out opening and thebag width of the bag.
